Flows of crude oil through a pipeline from the semi-autonomous Kurdistan region in northern Iraq to Turkey could restart soon after an almost two-year shutdown.

Iraq’s oil ministry repeated that it’s ready to restart exports from the semi-autonomous region of Kurdistan via a pipeline to Turkey that’s been shut for almost two years.

The U.S. has pressured Iraq to restart Kurdish oil exports via Turkey--and that pressure appears to be successful.

Turkey has yet to receive confirmation from Iraq on the resumption of oil flows through the Iraq-Turkey pipeline, Turkish Energy Minister Alparslan Bayraktar told Reuters on Wednesday.

Turkey says it has yet to hear from Iraq about restarting oil flows through an export pipeline from the semiautonomous Kurdistan region, casting doubt on expectations for an imminent resumption.
